This file details changes in 2.6 which affect PCMCIA card driver authors: This file details changes in 2.6 which affect PCMCIA card driver authors:
* Unify detach and REMOVAL event code, as well as attach and INSERTION
code (as of 2.6.16)
void (*remove) (struct pcmcia_device *dev);
int (*probe) (struct pcmcia_device *dev);
* Move suspend, resume and reset out of event handler (as of 2.6.16)
int (*suspend) (struct pcmcia_device *dev);
int (*resume) (struct pcmcia_device *dev);
should be initialized in struct pcmcia_driver, and handle
(SUSPEND == RESET_PHYSICAL) and (RESUME == CARD_RESET) events
* event handler initialization in struct pcmcia_driver (as of 2.6.13) * event handler initialization in struct pcmcia_driver (as of 2.6.13)
The event handler is notified of all events, and must be initialized The event handler is notified of all events, and must be initialized
as the event() callback in the driver's struct pcmcia_driver. as the event() callback in the driver's struct pcmcia_driver.
